The present invention relates more particularly to lead pencils of the so-called magazine type, wherein leads to be successively used in the pencil are stored and removed from said magazine when needed for use, the present invention being an improvement on that disclosed in my prior Patent No. 1,937,779, granted me on Decemher 5, 1933.

The primary object of the present invention is to provide a simple and eflicient magazine arrangement for such lead pencils, which is capable of economical production and highly efiicient in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of the specification and in which:

Fig. 1 is an enlarged sectional view taken through the tip end of a magazine pencil showing a magazine arrangement embodying the invention.

Fig. 2 is a section taken substantially on line 22 of Fig. 1.

Fig. 3 is a section taken substantially on line 3-3 of Fig. 1.

Fig. 4 is a perspective view of a magazine frame employed in the construction and shown removed from the pencil barrel.

Fig. 5 is a perspective view on a small scale of the complete pencil.

Fig. 6 is a view similar to Fig. 1, but showing a modified magazine arrangement.

Fig. 7 is a section taken substantially on lines I'I of Fig. 6.

Fig. 8 is a section similar to Fig. 7 but showing the magazine in a diii'erent position; and

Fig. 9 is a perspective view of the magazine removed from the pencil barrel.

The embodiment of the invention illustrated in Figs. 1, 2, 3, 4 and 5, comprises a pencil barrel I0 having a pencil tip II provided with a lead bore I2 in registration with a reciprocating plunger I3. The plunger I3 is carried by an operating head I l equipped with an eraser I5, best shown in Fig. 5. These parts of the pencil are identically the same as those disclosed in my said prior Patent No. 1,937,779, and require no further description here.

The barrel I9 is provided with a laterally opening magazine recess I 6 adjacent the tip I I, adapted and arranged to receive removably the inner end of a magazine frame I1. For this purpose the frame I1 is equipped with spring balls I8, arranged to engage notches I9, as best shown in Fig. 2. Notches 20 are provided as shown to facilitate removal of the frame I! from the barrel, as will be readily understood.

A cylindrical magazine 2| is rotatably mounted as indicated in the magazine frame I1, and is provided with a central bore or recess 22 having a tortional spring 23 arranged therein as shown. One end 24 of the spring 23 is attached, as shown, to the magazine 2 I, the other end 25 of said spring being attached as shown to the end of the magazine frame IT. The magazine 2I is provided with six lead pockets 26 arranged circumferentially 15 as shown so as to be brought successively into registration with the tip bore I2 and the plunger I3, the end of the frame I! being provided with a central bore 27 to permit of reciprocations of the plunger I3 through the pockets 26, and the bore I2, as will be readily understood.

By this arrangement it is to be noted that the plunger I3 may be readily manipulated to pass through the pockets 26, and into the bore I2 when desired. 25

The magazine 2I is provided with 3 peripheral slots 28, and a stop plate 29 is secured as shown to the inner face of the frame I1, and is provided with 3 stop fingers 3i] projecting into the slots 28, in positions to traverse the pockets 26 when the magazine 2| revolves. A sight opening 3| is provided in the outer wall of the frame I1 and corresponding numbers are placed on the periphery of the magazine 2| to indicate which of the magazine pockets is in registration with the lead bore 5 I2.

In use and in operation leads 32 are placed in the pockets 23, the magazine 2| being rotated as it is being filled, to place the tortional spring 23 under tension, each lead 32 being inserted behind the stops 30 to prevent reverse rotation of said magazine, as will be readily understood. Then the'magazine frame I! is inserted in the recess I6 and the pencil is ready for use. By depression of the plunger I3 the lead 32 aligned therewith is forced into the tip bore I2 and is utilized for writing until consumed, and as is more fully explained in my said Patent No. 1,937,779. When said lead has been consumed the plunger I3 is retracted. As soon as said plunger I3 is removed from the corresponding pocket 26, the spring 23 serves to step up the magazine 2| until the next successive lead encounters the stops 30, whereby said next lead is placed in registration with the lead bore I2 for use as above explained.

Thus each lead in the magazine pockets 26 may be successively brought into registration with the tip bore l2 and utilized in the pencil without refilling the magazine. By this arrangement a simple and effective magazine arrangement is provided for the pencil, which is capable of economical production and is highly efficient in use. In this connection it is also to be noted that the magazine arrangement is such as to be fully operable, notwithstanding the accidental breakage of any of the leads 32. V

In the modification illustrated in Figs. 6, 7, 8 and 9, a different magazine arrangement has been disclosed. In this arrangement the magazine recess I6 is rectangular in form to receive a rectangular magazine frame 33 having stop flanges 34 at its ends, there being notches 35 in the pencil barrel to facilitate removals of the magazine frame. The magazine frame 33 is made of a size to'snugly fit and to be frictionally held in the recess I 6'.

Arranged in the magazine frame 33 is a laterally shiftable rectangular magazine 36 having 3 lead pockets 31 therein, as shown. A leaf spring 38 is arranged in the frame 33 to force the magazine 36 normally inwardly to bring the pockets 3'! successively into registration with the bore l2, and plunger l3. Stop lugs 39 are struck from the sides of the frame 33 to project into notches 40 intersecting the lead pockets 31.

In use the magazine 36 is forced into the frame 33 and the pockets 3'! filled with leads, the outermost lead engaging the stops 39 to prevent return movement of the magazine. Then the magazine frame 33 is inserted in the recess IE to bring the innermost lead 32 into registration with the tip bore 12 and plunger I3, when the leads may be utilized by manipulations of the plunger [3, as before. As each lead is utilized, the spring 38 forces the magazine 36 inwardly to bring another lead into registration with the tip bore and plunger until the supply in the magazine is exhausted. This arrangement also constitutes a simple and efficient arrangement for the purpose which is capable of somewhat more economical production than the one already described, but does not contain as many leads. Here again the arrangement is fully operative, notwithstanding the accidental breakage of one or more of the leads.

While I have illustrated and described the preferred constructions for carrying the invention into effect, these are capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details described, but desire to avail myself of such variations and modifications as fall within the scope of the appended claims.
